Background technique

Technical field

Copolymer compositions can be used for preparing skin contact adhesive and/or coating in substrate.It discloses preparation and makes With the method for copolymer compositions.Copolymer compositions include organosiloxane copolymer.

Brief introduction

Various types of skin contact adhesives have been proposed for skin contact application such as medical adhesive tape Adhesive, the adhesive for prosthese, ostomy appliance adhesive, is used for medical monitor at the adhesive for wound dressing The adhesive of tool, for scar therapy treatment adhesive and transdermal drug delivery systems.Aqueous colloidal adhesive and propylene Acid esters adhesive usually has highest adhesion strength (for example, it is desired to ceiling capacity to remove from skin).Polyurethane binder With the second high adhesion strength, and siloxanes has the minimum adhesion strength of the skin contact adhesive of these types.With need It those of to remove adhesive compared with low energy to compare, there are skin contact adhesives of higher adhesion strength (to need higher for those Energy removes) during removal in may cause bigger pain and wound may be caused to skin.Certain skins connect Touching adhesive is also possible to leave unexpected residue on the skin during removal.

During chronic wound care, adhesiveness wound dressing and/or medical adhesive tape may during more change dressings In wound and cause pain and damage at wound circumference.Repeatedly apply and remove skin contact adhesive may bring pain and Wound, for the patient with delicate skin.Delicate skin is usually characterized by that skin is thin and is easy to tear, And it is more common in the elderly compared to other crowds.Aging, light exposure and heredity are the factor for causing thinning of skin. Some drugs (oral or topical corticosteroid is such as used for a long time) are it is also possible that the blood vessel in skin and skin becomes crisp It is weak, and make it easier to by wound associated with adhesive is removed.Individual with delicate skin can also occur in The situation that cohesive force between epidermis and corium and between corium and subcutaneous tissue is lost, this is easier these individuals There is a situation where skin lacerations and wound, especially when using the skin contact adhesive with higher adhesion strength.

In addition, silicone adhesive (for example, by two parts those of silicone elastomer preparation of catalysis) may be uncomfortable Such as transdermal drug delivery is applied for certain skin contact adhesives.It is used to prepare certain catalyst of silicone elastomer (such as, for the platinum metal catalysts of Si―H addition reaction) may negatively affect the medicinal actives in transdermal drug delivery device Ingredient.

In addition to skin contact adhesive, polyurethane and polysiloxane are also used for the painting being applied in various substrates Material.Known polyurethane has high mechanical tenacity, but has some defects, and such as temperature tolerance, moisture-proof and irradiation stability are limited.
